Today I got the let's "take it slow" this weekend. Last time I heard that I wound up in the friendzone. I'd that is what she is thinking, I may just flake and go no contact the next couple of days, and not go visit this weekend. First she sends panty pics then does a 360 to take it slow?Start pushing the boundaries with your conversations to see how she responds sexually. If she is good with it, then go spend a wknd. and stay at her place.
Stop thinking so much, ride the waves, and have some fun. That's all she really needs/wants right now and you can be that guy.
Be aware of your issues with why you have been put in the friend zone before. If you don't change your approach you'll end up there again with a woman that sounds pretty easy. You come across as super analytical, that mindset will always be a hurdle to success with women and its a turnoff.
